Take double-refined loaf sugar, pound and sift it through a lawn sieve; make a bay with the sugar on a marble slab, into which pour some dissolved gum, and mix it into a paste as you would dough, flavouring the mass with oil of peppermint. One ounce of this is sufficient for forty pounds of lozenges. Some persons prefer mixing their gum and sugar together at first in a mortar; but as it is indifferent which way is pursued, that may be followed which is most convenient. Roll out the paste on a marble slab until it is about the eighth of an inch in thickness, using starch powder to dust it with, to prevent its sticking to the slab and pin. Before cutting them out, strew or dust over the surface with powder mixed with lawned sugar, and rub it over with the heel of your hand, which gives it a smooth face. This operation is termed "facing up." Brush this off, and again dust the surface with starch powder, cut them out, and place in wooden trays. Put them in the hot closet to dry. Note. - All lozenges are finished in the same manner.
